Senior Estimator

AtkinsRéalis•Reno, NV

13d•$130,000 - $150,000

About The Position

AtkinsRéalis is seeking a Senior Estimator to join a team specializing in surface mining projects for processing plants and related infrastructure for clients across North America. Based in Henderson, Nevada, the role develops full-cycle capital cost estimates, from Estimate Plan through Basis of Estimate, for projects ranging from concept to feasibility and definitive levels. The Senior Estimator works with engineering, procurement, construction, and project controls disciplines, with support from the Estimating Manager, to deliver estimates on schedule. The role covers multidisciplinary estimates for surface mining scopes, including site development, processing facilities, and non-process support infrastructure. It also develops sustaining capital, reclamation, and closure estimates, establishes and benchmarks rates and productivity factors, evaluates contingency, prepares estimating plans and basis documents, and supports change management. The position contributes to estimating procedures, databases, benchmarks, lessons learned, and cross-disciplinary initiatives. The role is based in Henderson, Nevada, with flexibility to work from home and/or the office as required. Project or construction site visits may be required.

Requirements

8–10 years of progressive experience developing capital cost estimates for mining projects.
Demonstrated experience in multidisciplinary estimating.
Exposure to mining projects involving commodities such as gold, silver, copper, lithium, rare earths, iron ore, nickel, ferroalloys, aluminum, cobalt, or potash.
Sound foundation in generating unit rates for mining processing plant equipment and key bulk commodities.
Successful completion of an engineering four-year degree, college diploma, or equivalent technical program.
Excellent understanding of Microsoft Office and advanced knowledge of Microsoft Excel.
Ability to quickly interpret detailed information and communicate it at a higher level for reporting, discussion, and presentations.
Ability to manage and manipulate small to large data sets frequently and with ease.
Solid written and oral communication skills.
Commitment to a culture of workplace safety.
Exceptional multitasking, organizational, and problem-solving skills.
Flexibility to work from home and/or an office as required.
Ability to visit project and construction sites.

Nice To Haves

Estimating experience in carbon capture technologies, decarbonization projects, or green ammonia.
Experience with estimating software.
Asset management and life-cycle costing related to mining processing plants, ports, rails, or similar assets.
Programming capability in Microsoft Excel and/or Access.

Responsibilities

Develop full-cycle capital cost estimates for Conceptual, Order of Magnitude, Prefeasibility, Feasibility, and Definitive estimate classes, as outlined by AACE International.
Apply industry estimating methodologies and techniques to meet target accuracy ranges and project timelines.
Perform multidisciplinary estimating for surface mining scopes, including site development, processing facilities, and non-process support infrastructure.
Develop sustaining capital, reclamation, and/or closure estimates.
Maintain and contribute to AtkinsRéalis unit-rate databases and benchmarks, including developing unit rates from first principles and calibrating them against contractor data.
Establish labor rates and productivity factors for union and open-shop work in greenfield, brownfield, and operating-plant environments.
Benchmark key performance metrics for current and future estimates.
Develop field and non-field indirect costs from first principles.
Perform deterministic and support probabilistic contingency evaluations.
Prepare comprehensive Estimating Plans and Basis of Estimate documents.
Work independently and coordinate with other estimators as required to develop estimates.
Coordinate with planning and cost control disciplines on estimate inputs.
Support change-management workflows for existing projects, including Design Change Notices and Project Change Notices.
Implement estimate coding structures, including Work Breakdown Structures, Commodity Resource Coding, and procurement, construction, and engineering work packaging.
Use advanced Microsoft Excel functions to manage and manipulate data for costing, trending, reconciliation, and benchmarking.
Support the advancement of AtkinsRéalis Estimating Procedures and Guidelines for estimating and project controls.
Contribute to departmental initiatives, interdisciplinary collaboration, benchmarking, and implementation of lessons learned.
Present capital cost estimates to internal and external parties, including owners, auditors, and peer reviewers.
Visit project or construction sites as needed.
